Title: Steering mechanism with audible indication of deviation
IPC: B63H25/36
Filed: 1962-10-08
Abstract: 989,032. Photo-electric sensing devices. H. E. FLORY. Oct. 7, 1963 [Oct. 8, 1962], No. 37940/62. Heading G1A. [Also in Divisions B7 and G4] Apparatus for steering a vehicle comprises means whereby deviation from a predetermined course causes an audible signal which is cancelled when the steering correction necessary to return the vehicle to the course is applied. In a ships steering, Figs. 1, 2 the signal is generated by means of an arcuate slot 4 in the compass card 5, through which light is projected from lamp 6 on to two photo-cells 7, (phototransistors) the arrangement being such that when the ship is on course both cells produce the same output. Deviation from the course produces unequal signals in the cells 7 to actuate a balanced relay 10, and connected one or other of the oscillators 12, 13 to the loud speaker 3 via control unit 2. Application of the necessary steering correction produces an output from potentiometer 16 to cancel the signal. Circuit details, Fig. 3. The signal for actuating the balanced relay R1 is produced by a pair of photo transistors 20 illuminated from the lamp 6, and the two ends of the control potentiometer 16 is connected to the emitters of these transistors in parallel with a further potentiometer 23. This further potentiometer may be adjusted to provide a standing unbalancing bias if the ship's characteristics or weather conditions should require a continuous steering correction. The system also includes a sensitivity control 24 to adjust the sensitivity of relay 24 to the unbalance signal. The circuit of Fig. 3 also includes a function selection switch having ganged wafers S1a. . . S1e giving the following facilities:- (a) Oscillator and potentiometer 16 disconnected, so that deviation from course is indicated by extinguishing lamp 26 or 27. Cancellation of indication is given when the ship is back on course. (b) Operation as described in connection with Figs.1,2. (c) Power steering with the audible signal as a warning. (d) Power steering without the audible warning. The system may also include a plug-in remote control unit 33 in which movement of potentiometer 35 has the same effect as a deflection of the compass card. Specification 986,982 is referred to.

Abstract: 1488320 Liquid droplet recording apparatus INTERNATIONAL BUSINESS MACHINES CORP 22 Sept 1975 [16 Dec 1974] 38735/75 Heading G4H [Also in Division B6] Liquid droplet recording apparatus comprises means for producing a stream of liquid droplets, means for deflecting a group of droplets by increasing (or decreasing) amounts so that they are directed towards a corresponding group of target locations (1-15, Fig. 3), and selectively operable means for causing additional (or decreased) incremental deflection of individual droplets so that they are directed towards additional target locations (e.g. 81) between the first-mentioned ones. As described, an ink-jet printer prints each character as a 15 x 12 matrix using magnetically deflected ferro-fluid ink. Ink 22 from nozzle 20 is broken up into droplets by means of a magnetic exciter 24 (or alternatively a piezoelectric crystal or a magnetostrictive element) and subjected to a 21-drop-cycle raster deflection by magnet 36. Only drops 1-15 are used, so drops 16-21 (and any drop corresponding to a matrix point where printing is not required) are horizontally deflected by a magnet 30 into a catcher 29. Magnet 30 is also used to impart an incremental horizontal deflection (e.g. points 80, 82) while a magnet 40 is used to impart an incremental vertical deflection (e.g. 81, 82). The control circuit for the windings of magnets 24-36 is shown in Fig. 6. Controls 53, 54 comprise shift registers connected to two drivers for coil 31 of magnet 30 for large and small amplitude pulses (catcher 29 and incremental deflection). Control 55 comprises two shift registers, one acting as a delay since magnet 40 is 10 drops downstream of magnet 30.

As shown, the pressure of ink from a pump 13 to the printer is measured by sensor 20, compared with a reference, and, at times corresponding to spaces between printed characters or lines, is used to control the amplitude or frequency of an oscillator driving the pump i.e. to regulate the ink pressure. Alternatively the pressure may be controlled in accordance with the ink temperature as sensed by thermocouple 2. In another embodiment, Fig.2 (not shown), the pressure is regulated to a value which is modified according to the ink temperature error, to allow for variations in the ink viscosity. In a further embodiment, Fig.3 (not shown), the velocity of the jet is measured, using a digital counter or ramp voltage to time the jet between two proximity detectors, to vary the pump excitation and thus regulate the jet velocity. In yet another embodiment, Fig.4 (not shown), the position of the jet, as deflected between electrodes, is measured and regulated by varying the pump excitation. The pump may be of the flexible chamber type (see Division F1).
